Sometimes, suppliers quote the different models based on the centre height above the Cross Slide, where the Toolpost sits, or provide dimensions of the Tool Holders, so that you can work out which size you need, based on the size of the tooling that you use, and the stud that retains the Toolpost.

Rather than a QC toolpost, a single tool holder might be a better idea. I find, especially when trying to turn something slim, that the tailstock barrel often prevents the 4 way turret from approaching the work any closer than about 10 or 12 mm. This then results in canting the tool around anticlockwise whilst simultaneously rotating the 4 way turret clockwise in order to allow the tool overhand to be reduced as much as possible.

The Warco 220 was actually a Mashstroy made in Bulgaria and that lathe is mentioned/listed on the Lathes UK site, so info might be gleaned there…….
